That would integrate them into the site, but that's not necessarily the wisest navigation system. You don't want to link to that many pages globally, as that can dissipate PageRank to other optimized pages and can lose focus for the search engines. I suggest some sort of hierarchical navigation structure.
See this current discussion in the Google Search forum...
The "Mega Menu" Problem and Google Rankings
When you say "page ranking," are you confusing ranking in the serps with Google PageRank? They are two different things.
Adding a lot of pages does not automatically add PageRank to the site. That's a common misconception. What adding a lot of pages does, if they are good and useful content, is to make your site more attractive for inbound links... and to offer more opportunities for them. Whether knowledgebase content is linkworthy depends very much on your topic and your niche market.
If these pages do start ranking well and do attract inbound links (and that's important), then they can help the site as a whole by distributing "link love" throughout the site. A lot depends on your internal navigation and how your pages relate to each other.
But, rankings are query specific and page specific.
Study the home page navigation on DMOZ to see how users and linking influence are channeled to the most important pages. Your site may not look like DMOZ, but the way the navigation from the home page is prioritized is an important lesson.
